What does VSEPR stand for?
Valence Shell Electron Pair Rotation
Variable Shell Electron Pair Repulsion
Variable Shell Electron Pair Rotation
Valence Shell Electron Pair Repulsion
What determines the 3D shape of a molecule according to VSEPR theory?
The presence of hydrogen bonds
The number of core electrons
The number of valence electrons
The arrangement that minimizes electron pair repulsion
Why does beryllium dichloride form a linear shape?
Because it wants to minimize electron pair repulsion
Because it follows the octet rule
Because it has double bonds
Because it prefers a 2D structure
What shape does BF3 form?
Linear
Tetrahedral
Trigonal planar
Bent
Why do molecules with a trigonal planar shape have a 120-degree bond angle?
Because of the presence of triple bonds
To minimize repulsion between electron pairs
To accommodate lone electron pairs
To minimize repulsion between double bonds
What causes the bent shape in SO2?
A linear arrangement of atoms
A double bond
A triple bond
An unshared electron pair
What is the bond angle in a tetrahedral molecule?
120 degrees
180 degrees
109.5 degrees
107 degrees
What shape does NH3 adopt?
Linear
Tetrahedral
Bent
Trigonal pyramidal
How does the presence of lone electron pairs affect the bond angle in NH3 compared to a tetrahedral shape?
It increases the bond angle
It decreases the bond angle
It makes the bond angle variable
It does not affect the bond angle
What is the bond angle in water (H2O)?
107 degrees
109.5 degrees
105 degrees
120 degrees
